TITLE : SOLAR SYSTEM
                                                                                                                       YEAR : 5

           THE  SOLAR SYSTEM  CONSIST OF NINE PLANETS THE SUN, NATURALSATELLITES,   METEORS, COMETS AND ASTEROIDS.

           1. THE NAMES OF THE NINE PLANETS ARE :
           
            MERCURY

            VENUS
 
             EARTH

              MARS

              JUPITER

              SATURN

             URANUS

             NEPTUNE

             PLUTO

              2. THE PLANETS MOVE AROUND THE SUN IN AN ORDERLY MANNER.

              3. THE PLANETS MOVE ALONG THEIR OWN PATHS CALLED ORBIT
                     WITHOUT CROSSING EACH OTHERS PLANET.
                
               4. THE GRAVITATIONAL FORCE BETWEEN THE SUN EACH PLANET 
                     KEEPS EACH PLANET FROM FALLING OUT THEIR ORBIT.

               5. IN TERMS OF SIZE OF THE SUN, IS  THE BIGGER FOLLOWED BY
                    THE EARTH AND THE SMALLEST BEGINNING HE MOON.     
         
               6. THE SUN PROVIDES LIGHT AND HEAT WARMTH.

                7. THE FURTHER THE PLANET ALWAYS FROM THE SUN. THE COOLER 
                     IT IS.

                8. THE NEARER THE PLANET TO THE SUN, THE WARMER IT IS. 

                9. WHEN THE PLANET IS TOO HEAT, IT CANNOT SUPPORT LIFE.

               10. THERE MUST BE AIR, WATER AND FOOD ON A PLANET IN ORDER TO

CONGRATULATIONS !  GOOD TRY!!!!!!!
                                                                                            

DEAR PUPILS LET US LEARN ABOUT THE PLANETS!




                          
                        CAN YOU TELL ME TELL HOW MANY PLANETS ARE THERE?





LET US READ THE NAMES OF THE PLANETS ......







VERY GOOD  CHILDREN! NOW I HAVE ATTACHED NOTES ABOUT THE PLANET FOR YOU

REAN AND UNDERSTAND. I HOPE THE NOTES WILL HELP YOU TO DO THE EXERCISES

GIVEN.   




WATCH THE MOVEMENT OF THE PLANETS! ITS AMAZING...


LABEL THE PLANETS CORRECTLY.









CLOUD IN THE SPACE

ON A CLEAR NIGHT , A POWERFUL TELESCOPE REVEALS SEVERAL DIM, FUZZY PATCHES OF LIGHT BETWEEN THE STARS . SOME OF THESE ATE DISTANT GALAXIES, BUT OTHERS ARE GIGANTIC CLOUDS IN YHE SPACE CALLED NEBULAE.STARS ARE BORN IN SOME NEBULAE , AS DUST AND RHE GAS IN THE CLOUD ARE PULLED TOGETHER BY GRAVITY.



CIRCLING PLANETS

ERATH IS NOT ALONE IN THE SPACE .INCLUDING EARTH, NINE PLANETS CIRCLE , OR ORBIT , THE SUN . THEY MOVE AROND IN THE SAME DIRECTION, IN ELLIPTICAL ORBITS, AND RAE HELD IN THE PLAVE Y THE PULL OF THE SUN'S GRAVITY. MANY OF THE PLANETS ARE TINY CHUNKS OF THE ROCKS CALLED ASTEROIDS. TOGETHR , ASTEROIDS ARE CALLED THE SOLAR SYSTEM.



DEAR PUPILS , CAN YOU NAME ALL THE PLANETS IN THE SOLAR SYSTEM IN
THE CORRECT SEQUENCE ? LETS TRY.....


                                                             VERY GOOD!

Introduction About Solar System

The Solar System
1.     The Solar System is the name given to the Sun and all the bodies that move around the Sun.
2.     The Solar System consist of
(a)            The Sun
(b)           The nine unknown planets and their natural satelites ( moons),
(c)Other bodies such as asteroids, meteoroids and comets.

The Sun
1.     The Sun is the largest body in the Solar System.
2.     A planet does not give out its own light or heat. It shines because of the reflection of sunlight that falls on its surface.
3.     At the present , there are nine known planets. The planets , with increasing distance from the Sun are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune dan Pluto.
4.     Each planet spins by itself. It also moves around  the Sun in a ladge oval path called an orbit.
5.     Most of the planets have their other smaller bodies moving around them. These bodies are called natural satelites or moons.


The perfect placement of the Earth in the Solar System

MERCURY                          ----- Closest planet to the Sun
                                                       Dry and almost airless
                                                       Very hot days and very cold nights
                                                       Solid planet with rocky and crated surface

VENUS                                 ------ Closest planet to the Sun
                                                        Greenhouse  gases  trap heat from the Sun.Thus,
                                                        It is the hottest planet in the Solar System
                                                        Solid planet with rocky surface 

 EARTH                                 ------ Third planet from the Sun                                             
                                                           Only planet with water and air to support life
                                                            Moderate and suitable temperature for living things
                                                              Solid planet with rocky surface

MARS                                    ------ Cold planet with very thin atmosphere of
                                                             Very little water all water frozen
                                                           Solid planet with red rocky surface. It is called
                                                           ‘ the Red Planet ’


JUPITER                             ------ Largest planet in the Solar System
                                                           Made up of gas
                                                            Its atmosphere is very cold and stormy with
                                                           Strong winds and lighnings


SATURN                              ------ Second largest planet  in   the Solar System
                                                       Has beautiful rings made up of rocks and  ice
                                                        Made up of gas
                                                        Colder than Jupiter


URANUS      ------                         Made up of gases
                                                         Much colder than Saturn because it is very far  From the Sun
                                                      


NEPTUNE   ------                           Made up of gases
                               Very much like Uranus but  slightly   smaller
                                 As cold as Uranus


PLUTO          ----                          - Smallest and lightest planet in the  Solar System
                                                          A mixture of rock and ice
                                                            Colder than neptune
